6. MAINTENANCE 
 
After installation, the CleanWave
®
 filter requires almost no maintenance. 
We only recommend a periodic (e.g. annual) inspection. 
 
This inspection must be done with no voltage by a qualified technician
 
The working sequence is the following : 
 
Switch off the power of the CleanWave
®
 filter. 
 
Open the housing in order to access the filter.  In the case of the IP21 CleanWave
®
 filter,  
 
Unscrew and remove the lower part of the front panel (see fig. 3 and 7). 
 
Check that there is no voltage on the terminals.  
 
Visually check the general aspect of the filter, especially that there is no excessive dust on 
the Lo and Zo chokes.   
 
If necessary, clean the Lo and Zo with compressed air or with a vacuum-cleaner. 
 
Check the tightening of the power terminals. 
 
Close the housing. 
 
Power up the filter.
